PC Ti6 pipe with 2 s/a screens?

I took the spark arrestor insert out of my new Ti6 pipe, and I looked inside with a flashlight and there is another screen in there, looks like its not removable. I cant believe it could have a 2nd unremovable screen its a 2018 KX450F. Not the Pro pipe the regular Ti6. has anyone had any experience with this? I know I should call PC but I like to see what riders on vital say someone usually knows their shit
